I'm looking for the best possible locker to use on my blazer, it doesnt have to be fancy but I want something that will def help my lil old 2wd not get stuck as much as it usually does, well I'm hoping for a lot of responses on this one *crosses fingers*

 

If you're looking for better wet/snow traction then a locker maybe the wrong part for your truck. You would be better off with a limited slip/posi-traction rearend...

 

I would suggest the limited slip rear diff. There is less chance of things breaking when you have a clutch pack gradually applying than having a metal lever "locking" the axles suddenly with a lot of force.

 

well see the thing is I'm not looking for better traction in like wet/snow I'm looking for better traction in like sand, rocks, ruts, etc. I was told by han3r to get som all-terrain tires that way they wont dig in to the sand and will keep me on top of it and the only thing different from mud tires is that the mud tires will go through mud a lot easier ( whodathunkit, lol ) anyways yeah that's my whole long explanation, hope it went into enough explanation.

 

The bfg all terrains I had I hated in the mud, the small tread that made on road driving great quikcly filled with mud and wouldnt clean. I have mud terrains now and their great but sand/rocks the all terrains should do the trick. As for lockers theres the detroit, thats pretty popular or ARB. If you have the money I'd go with a selectable locker if I were you. Then you dont have to worry about the nice little quirks of driving and turning with a locker on the road

 

Good post there.
Little quirks he is refrerring to would be things like the butt end sliding out from under you in turns, or jumping a lane when the locker engeages or disengages. Plus a clicking sound. Not all lockers are like that. Each type of locker has its own little quarks.

Like the Aussie locker is always locked, however it has a slip to it so the tires can turn at different speeds in turns. Being locked all the time stops it from the engageing/unlocking problem. Lock-right I think is another verision of LunchBox Locker like the Aussie.

Trouble with limited slips off pavement is the nature of how they work. They dont fully engage both tires on the axle until you have lost all traction on one tire. Plus a limited slip can grenade when you go from spinning tires to solid traction. That shock load places too much stress on the clutch packs and things go flying everywhere. Even through the diff cover.

With a selectable locker you can get full lock when you want it, and have a open differntial when you want it. However you pay for it. >$800 or so.

Detroit Lockers are by far the most known and respected for off-road durability and traction. Around $600 or so.

Lunchbox lockers are int eh $200-$400 range.

Limited slips are in the $200-$300 range. They are good for the street, and so so for off-roading.

Spolls and mini-spools are a little less then $200. But they permenately lock both tires together on teh axle. Eats tires due to scrubing while turning.

Critical things to think about.
During every turn every tire on your truck turns at a differnet speed and follows its own path. No two tires turn at the same speed and no two tires follow each other in a turn.

Lets keep the questions and info flowing guys. Maybe we can make this a good thread to point others to when this question comes up again, and it will come up again. Need more info, opinions on which is a better type of locker for each application, and who makes them.
